Voyager 1 exits solar system, takes Bach with it

Voyager 1, the NASA space probe that left Earth in 1977, has officially exited the solar system and is now the first manmade object to enter interstellar space. And it took with it classical music.

NASA on Thursday made the big announcement that the probe, which is 12 billion miles from the sun, probably left the solar system a year ago.

Among the objects Voyager 1 is carrying as it travels toward deep space is the so-called "Golden Record" -- a 12-inch gold-plated copper disk that contains greetings, images, sounds and recordings of music intended to be heard by extraterrestrial intelligence.
